The following table lists the minimal set of XTI system variables from \fB\fR that can be returned by \fBt_sysconf()\fR, and the symbolic constants, defined in \fB\fR that are the corresponding values used for \fIname\fR. .sp .sp .TS box; c | c l | l . Variable Value of Name _ T_IOV_MAX _SC_T_IOV_MAX .TE .SH RETURN VALUES .sp .LP If \fIname\fR is valid, \fBt_sysconf()\fR returns the value of the requested limit/option, which might be -1, and leaves \fBt_errno\fR unchanged. Otherwise, a value of -1 is returned and \fBt_errno\fR is set to indicate an error. .SH VALID STATES .sp .LP All. .SH ERRORS .sp .LP On failure, \fBt_errno\fR is set to the following: .sp .ne 2 .na \fB\fBTBADFLAG\fR\fR .ad .RS 12n \fIname\fR has an invalid value. .RE .SH TLI COMPATIBILITY .sp .LP In the \fBTLI\fR interface definition, no counterpart of this routine was defined. .SH ATTRIBUTES .sp .LP See \fBattributes\fR(5) for descriptions of the following attributes: .sp .sp .TS box; c | c l | l .
